I'm, like. 80-90% sure that didn't drive any more votes towards trump than obama being in front of a camera at all did.
... also, how in the hell is that mocking someone? I've listened to talk radio before, and that. That was not mocking. That was barely even blunt compared to the bile those things spew out daily.
For reference, folks that don't want to look at the (unnamed url -- it's a very short snippet from Obama's economy speech on June 1st) youtube video and possible start getting really annoying things junking up their suggested video results,
I hope you don’t mind me being blunt about this, but I’ve been listening to this stuff for a while now. (Laughter.) And I’m concerned when I watch the direction of our politics. I mean, we have been hearing this story for decades. Tales about welfare queens, talking about takers, talking about the “47 percent.” It’s the story that is broadcast every day on some cable news stations, on right-wing radio, it’s pumped into cars, and bars, and VFW halls all across America, and right here in Elkhart.
And if you’re hearing that story all the time, you start believing it. It’s no wonder people think big government is the problem. No wonder public support for unions is so low. (Applause.) No wonder that people think that the deficit has gone up under my presidency when it’s actually gone down. (Applause.) No wonder that -- they did a survey, a lot of white Americans think reverse discrimination is as big a problem as discrimination against minorities, even though black unemployment is twice as high as white unemployment. And the typical Hispanic woman makes 55 cents for every dollar a white man earns, and there are only a handful of women running Fortune 500 companies.
But that’s the story that’s been told. And I’m here to say, Elkhart, seven and a half years since I first came here, we’ve got to challenge the assumptions behind this economic story. (Applause.) And the reason is it has ended up dividing Americans who actually have common economic interests and should be working together for a better deal from the people who serve them. And it’s made people cynical about government, and it’s kept working families from pushing our political system to actually address our economic challenges in a realistic way. Families of all races, and all backgrounds, deserve higher wages. Families of all races, and all backgrounds, deserve quality health care and decent retirement savings. (Applause.) Every child in this country deserves an education that lets them dream bigger than the circumstances in which they’re born. (Applause.)
I bolded the bit from the video itself, to better render said video superfluous. That was the entirety of it, put under the label of "President Obama MOCKS Whites Who Believe in Reverse Racism (6/1/16)".
